Bagua with Taiji

Also known as: Eight trigrams; Pa Kua

The Bagua diagram arranges eight trigrams around Taiji, the symbol of complementary yin and yang forces.

About this symbol

The octagonal diagram presents the complete cycle of eight I Ching states. Taiji occupies the center: dark and light flow into each other, while the dots show that each force contains the seed of its complement. The surrounding trigrams describe patterns of change rather than fixed labels. Their positions vary between the Earlier Heaven and Later Heaven arrangements, so the specific sequence matters in practical interpretation. Esoteric reading: in divination the sign represents an archetypal movement of qi and suggests which quality should be cultivated, balanced, or released. In feng shui it is associated with a direction, an element, and an area of life.
